Infielder D.J. Peterson was selected by the Seattle Mariners and scout Chris Pelekoudas in the 33rd round of the 2010 amateur draft. However, he did not sign, opting to attend the University of New Mexico instead. He was selected in the first round of the 2013 amateur draft, 12th overall by the Mariners, and became the highest pick ever out of UNM. His brother Dustin Peterson was taken in the second round as well. D.J. soon signed for a bonus of $2,759,100 and made his pro debut with the Everett AquaSox on June 19th, going 0-for-3 against the Tri-City Dust Devils.
